自身外周血造血于细胞移植（PBSCT）术已成为急性白血病缓解后治疗的重要措施，但术后仍有较高的复发率，探索与复发有关的因素有利于PBSCT的进一步完善。我们用多聚酶链反应（PCR）技术对完全缓解期急性淋巴细胞白血病（ALL）患者外周血微量残留病（MRD）进行了检测，并对其临
Peripheral blood hematopoietic-cell transplantation (PBSCT) has become an important measure for the treatment of acute leukemia after remission, but there is still a high recurrence rate after surgery. The exploration of relapse-related factors is conducive to the further improvement of PBSCT. We used polymerase chain reaction (PCR) technology to detect minimal residual disease (MRD) in peripheral blood of patients with complete remission acute lymphoblastic leukemia (ALL) and to
